Abstract
In this work, we present the fabrication of hollow steel microneedles for transdermal drug delivery. Hollow steel microneedles are fabricated by laser ablation technique using femto second laser micromachining. A 4x3 array of rectangular microneedles with circular holes are fabricated. The processed hollow steel microneedles are 700 μm in height with 60 μm and 150 μm inner and outer diameters respectively.
